Expressions using animal names to describe ideas occur frequently in stories.
To make students aware of this, begin by writing the phrase "lion's share" on the chalkboard.

Invite discussion and add phrases suggested by students, such as "eager beaver," "dog's life," "swan song," "wolf's clothing," "eagle eye," "monkeyshines" and "bear hug."

Make a second list using the names of body parts: "leg of a journey," "mouth of a river," "spine of a book," "brow of a hill" and "bottleneck."

Have the children copy the lists and add to them as they encounter similar expressions in their reading.
